Title: Electronically controlled mechanical timepiece
Inventor: MOGI MASATOSHI
IPC: H02K7/18
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To provide an electronically controlled mechanical timepiece the duration of which can be prolonged, by reducing the occurrence of eddy current losses in metallic members near a rotor magnet. SOLUTION: In an electronically controlled mechanical timepiece, a nonmagnetic material not plated with nickel, etc., is particularly used for an outer dial 17 when an end stone guide 19c and the dial 17 are arranged in an overlapping state within the double of the gap G1 between a rotor magnet 13a and a stator 21. Consequently, the occurrence of eddy current losses in each metallic member can be suppressed by reducing the magnetic flux which is interlinked with the end stone guide 19c by reducing the leakage magnetic flux to the metallic member from the rotor magnet 13a. Therefore, the duration of the electronic control type mechanical timepiece can be prolonged, because the timepiece can be operated with less spiral spring energy by preventing the increase of the torque required for rotating a rotor 13.

Filed: 1989-04-05
Abstract: PURPOSE:To improve transporting efficiency by detecting the crowdedness in each riding cage in its inside or outside and artificially or spontaneously promoting, limiting or inhibiting passengers to get on and off the riding cage in accordance with the detected crowdedness. CONSTITUTION:First before a fixed time a high speed-large capacity continuous transporter 1 arrives at the corresponding on-off getting platform 2, escalators 3, serving as a guide device for passengers, are started operating, and the passenger is left as previously transported to the platform 2 to an extent such that it is not crowded for a riding cage 4.

Title: Flaw detection probe
Inventor: GOTO MOTOHARU
IPC: G01N27/90
Filed: 1986-04-14
Abstract: PURPOSE:To achieve a higher detection sensitivity, by winding a probe body with a pair of coils in a manner that they made an angle of inclination to an imaginary section passing the axis center of the probe body and at a fixed interval. CONSTITUTION:A probe body 1 is wound with a pair of coils 6 and 7 in a manner that they made an angle alpha (0<alpha<90 deg.) of inclination to an imaginary section passing the axis center 0 of the body 1 and at a fixed interval 8 and each one end of both the coils 6 and 7 is connected to a bridge circuit 5. Therefore, when energized, both the coils 6 and 7 form a magnetic field thereabout and hence, for example, when the probe is inserted into an object to be inspected as pipe body, as the coils 6 and 7 are connected to each one arm of the circuit 5, the output is balanced giving zero amplitude unless there is a change in the magnetic field, that is, that in the impedance by both the coils 6 and 7. This also minimizes the effect from the outline of the body to be inspected. Thus, when the probe is inserted into the object being inspected and the coils 6 and 7 are made to approach a part to be inspected, it can effectively detect a defect, corrosion and conductive foreign matter whatsoever at the part being inspected.
